Health related quality of life is the subjective experiences or preferences expressed by an individual, or members of a particular group of persons, in

relation to specified aspects of health status that are meaningful, in definable ways, for that individual or group

Several questionnaires have been proposed and adopted to assess QoL

The user is asked to answer to a predefined set of questions about her/his mental and psychological status and feeling

Why

3

Aimed at helping answer basic questions about the state of the user, such aso “is she depressed?”o “has she decreased her activity level?”o “is she more engaged in social

interactions?”

Preliminary results

15

BackHome, the first European research project aimed at delivering the ambitious, but critical, step to bring BNCI systems to mainstream markets

Where

Aimed at producing applied results, developing

o new and better integrated practical electrode systems

o friendlier and more flexible BNCI software

o better telemonitoring and home support tools

16

Further experiments are currently running to assess the effectiveness of the proposed methodology

What’s next?

In November, the system will be installed at BackHome end-users’ homes in Belfast

We are also considering data coming from social activities to assess, apart “Mobility”, also “Mood”

17

Closing remarks

A generic methodology to automatically assess quality of life of disabled people based on sensor-based telemonitoring

Preliminary experiments to assess “Mobility”

Preliminary results with a healthy user showed that the proposed methodology is promising

The work is part of the BackHome EU project

In November, experiments with real end-users will start in Belfast

Thanks for your

attention!
